ESP 32 & Bluetooth Low Energy (BLE)

Is there anyone around these parts that is familiar with the ESP32 & BLE? For my senior desing project, I’m building an alert system using 2 ESP32’s one as a BLE client & one as the BLE server.

The problem is, when the client disconnects, I get a HEAP error.

00:02:33.902 -> CORRUPT HEAP: Bad head at 0x3ffdec90. Expected 0xabba1234 got 0x3ffdef3c
00:02:33.902 -> assertion "head != NULL" failed: file "/home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/heap/multi_heap_poisoning.c", line 214, function: multi_heap_free

I’ve been stumped on this for a bit & can share more code if anyone thinks they’re interested in helping.

I’d be willing to take a look at the code. I’ve been working with the esp32 for a couple different projects recently, though I haven’t used the Bluetooth at all yet. Usually when I have issues like this it’s some kind of dumb memory related mistake that I’ve made; using pointers that are no longer valid, running past array limits, etc. I also have a couple of the esp-prog jtag debuggers which can be helpful.

What environment are using? Esp-idf or Arduino? Have you decoded the backtrace?
